Ticket to Ride: Europe takes you on a new train adventure across Europe. From Edinburgh to Constantinople and from Lisbon to Moscow, you'll visit great cities of turn-of-the-century Europe. Like the original Ticket to Ride, the game remains elegantly simple, can be learned in 5 minutes, and appeals to both families and experienced gamers. Ticket to Ride: Europe is a complete, new game and does not require the original version.

More than just a new map, Ticket to Ride: Europe features brand new gameplay elements. Tunnels may require you to pay extra cards to build on them, Ferries require locomotive cards in order to claim them, and Stations allow you to sacrifice a few points in order to use an opponents route to connect yours. The game also includes larger format cards and Train Station game pieces.

The overall goal remains the same, collect and play train cards in order to place your pieces on the board, attempting to connect cities on your ticket cards. Points are earned both from placing trains and completing tickets but uncompleted tickets lose you points. The player who has the most points at the end of the game wins.

Three tuckboxes: one for destination tickets, two for train cards. All boxes have box and card art all over. The size fits cards with ArcaneTinmen sleeves, and may also fit with other sleeves, but YMMV.

One-page summary of the rules for the different flavors of Ticket To Ride. This is meant as a summary for those who already know the rules. Thanks to the BGG commumnity for helping me keep this as accurate as possible!
EDIT: Correction to role of Locomotives as wildcards in Nordic countries (thanks to user 'duckworp'!).

This rule summary contains all the rules for TTR: Europe.
I used them as follows: I printed five of these as well as five small maps for the game. I then glued two of each together, to create a nice double-sided player aid for every player.
